机器学习中的多种分类方法的matlab代码，程序正确可用，传上来一起分享交流。每个代码文件里面注释齐全，适合自学。

我用matlab自己写的一个三维粒子群算法的程序，不是很精简，有简化的空间，但是功能还是很全面的，注释略多，看不惯可以自己删哈哈

混合动力车辆整车仿真模型，通过simulink搭建完成。内含驾驶员模型、控制策略模型、发动机模型、电机模型、变速箱模型、车辆动力学模型

1.寄存器部分参考了原子和网上其他大佬的代码，稍作修改；2.可快速更改控制引脚和控制方式（spi和i2c），在.h文件中修改即可；3.对字符显示进行优化，目前可显示字符、字符串、符号十进制、可选精度小数、十六进制...4.封装了绘图函数，绘制圆、椭圆等；5.封装对屏操作函数，移屏、翻转等，可用于制作菜单；

就看不惯要5分的人，辛辛苦苦攒的分根本不够用，呜呜呜，我好不容易搜集的哦，我只要2分，不满意的话。。。。。。。我也没办法了
